The Artemis I Mission is scheduled to launch Monday morning, and leaders from NASA and their partners on Friday discussed the steps being taken to advance human exploration.

Friday’s postponement news came after SpaceX chief Elon Musk disclosed he had gotten mixed test results for COVID-19 and was awaiting the outcome of a more definitive test. “So ‘Elon Musk Tests Negative for Covid’ is an equally correct title,” he tweeted. Four astronauts — three Americans and one Japanese — are scheduled to rocket to the International Space Station on Sunday night. The upcoming crew flight comes just three months after the end of the test flight with Hurley and Bob Behnken, both NASA astronauts. NASA and SpaceX are especially eager to retrieve this first-stage booster; it will be used for the next crew launch.

The Hurricane Center said it expected the storm to make landfall early Tuesday near southern North Carolina. Still, on this part of the South Carolina and North Carolina coasts that has been affected to varying degrees by seven tropical storms or hurricanes since 2014, residents weren't panicking. Up the coast in southern North Carolina, high winds from Isaias’ inner core knocked down trees and power lines, blocking roads. Wayne Stanley and his family came to the city over the weekend from Julian, North Carolina. Farther up the coast into North Carolina, the hurricane center predicted storm surges of 3 to 5 feet (0.9 to 1.5 meters) when Isaias moves onshore.

The two NASA astronauts returned to Earth on Sunday in a dramatic, retro-style splashdown carried out by Elon Musk's SpaceX company. Two days after returning from the International Space Station, NASAs Bob Behnken described in vivid detail their wild ride home. Once we descended a little bit into the atmosphere, the Dragon really, it came alive, Behnken said from NASA's Johnson Space Center in Houston. SpaceX became the first private company to send astronauts into orbit with the May 30 liftoff from NASA's Kennedy Space Center, ending a nine-year launch drought from home soil for NASA astronauts. It was the first splashdown for NASA astronauts in 45 years.

Beach goers watch waves churned up by Tropical Storm Isaias near Jaycee Beach Park, Sunday, Aug. 2, 2020, in Vero Beach, Fla. Isaias weakened from a hurricane to a tropical storm late Saturday afternoon, but was still expected to bring heavy rain and flooding as it barrels toward Florida. Isaias was downgraded from a hurricane to a tropical storm Saturday afternoon, but was still expected to bring heavy rain and flooding as it crawled just off Florida's Atlantic coast. In Indian River County, north of West Palm Beach, Florida, emergency shelters were clearing out Sunday after Isaias was downgraded to a tropical storm. A tropical storm warning was in effect from Hallandale Beach, Florida, to South Santee River, South Carolina, and for Florida's Lake Okeechobee. Curt Anderson in St. Petersburg, Cody Jackson in Palm Beach County, Florida, and Julie Walker in New York contributed.

The return clears the way for another SpaceX crew launch as early as next month and possible tourist flights next year. Welcome back to planet Earth and thanks for flying SpaceX, said Mission Control from SpaceX headquarters. It was the first time a private company launched people into orbit and also the first launch of NASA astronauts from home turf in nearly a decade. SpaceX already had experience hauling cargo to the space station, bringing those capsules back to a Pacific splashdown. SpaceX needs six weeks to inspect the capsule before launching the next crew around the end of September.

In this image from video made available by NASA, astronauts Doug Hurley, left, and Bob Behnken prepare for undocking from the International Space Station, aboard the SpaceX Crew Dragon capsule on Saturday, Aug. 1, 2020. Space station commander Chris Cassidy rang the ship's bell as Dragon pulled away, 267 miles (430 kilometers) above Johannesburg, South Africa. The astronauts' homecoming will cap a mission that ended a prolonged launch drought in the U.S., which has relied on Russian rockets to ferry astronauts to the space station since the end of the shuttle era. The flag which also flew on the first shuttle flight in 1981 became a prize for the company that launched astronauts first. The next SpaceX crew flight is targeted for the end of September.

Astronauts returning in the early 1970s from Skylab, NASAs first space station, did not feel well following splashdown, Hurley noted. Feeling sick is the way it is with a water landing, he said during the crews final news conference from the International Space Station. The capsule has been docked at the space station since May 31, allowing Hurley and Behnken to chip in with spacewalks and experiments. The plan is for the Dragon to undock from the space station on Saturday, a day before splashdown. We wont leave the space station without some good landing opportunities in front of us, good splashdown weather, Behnken told reporters.

On Wednesday, July 29, 2020, SpaceX and NASA cleared the Dragon crew capsule to depart the International Space Station and head home after a two-month flight. (NASA via AP)CAPE CANAVERAL, Fla. Tropical weather barreling toward Florida could delay this weekends planned return of the first SpaceX crew. On Wednesday, SpaceX and NASA cleared the Dragon crew capsule to depart the International Space Station and head home after a two-month flight. SpaceX is already preparing to launch a second crew to the space station at the end of September. NASA wants six weeks between the splashdown and the launch of the next Dragon crew, for capsule inspections and reviews.

CAPE CANAVERAL, Fla. The commander of the International Space Station said Monday that losing a mirror during last weeks otherwise successful spacewalk was a real bummer.NASA astronaut Chris Cassidy said he has no idea how the small mirror on his left sleeve came off. The band for the mirror is on pretty tight, he noted, and it may have caught on a metal tether attachment as he exited the airlock Friday. That was a real bummer for me.Hell use a spare for Wednesdays spacewalk, the second of four he and NASA astronaut Bob Behnken will do to replace old station batteries.

CAPE CANAVERAL, Fla. A spacewalking astronaut added to the pieces of junk orbiting the Earth on Friday, losing a small mirror as soon as he stepped out of the International Space Station for battery work. Commander Chris Cassidy said the mirror floated away at about a foot per second. Spacewalking astronauts wear a wrist mirror on each sleeve to get better views while working. Cassidy and Bob Behnken, who followed him out without mishap, were conducting the first of at least four spacewalks to replace the last bunch of old station batteries. ___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institutes Department of Science Education.

Amateur astronauts, private space stations, flying factories, out-of-this-world movie sets this is the future the space agency is striving to shape as it eases out of low-Earth orbit and aims for the moon and Mars. But the future is incredibly exciting, NASA astronaut Kjell Lindgren said the day before SpaceXs historic liftoff. The ticket price which includes 15 weeks of training and more than a week at the space station is about $55 million. Beginning in 2024, Axiom plans to build its own addition to the 260-mile-high (420-kilometer-high) outpost to accommodate its private astronauts. SpaceX still has to get NASA astronauts Doug Hurley and Bob Behnken safely back to Earth this summer in its Dragon capsule.

(NASA via AP)CAPE CANAVERAL, Fla. The first astronauts launched by SpaceX declared victory Monday in NASAs cosmic capture-the-flag game. The flag flew on the first space shuttle flight in 1981 and the final one in 2011. The flag was an added incentive for Elon Musk's SpaceX company and Boeing, competing to be the first private company to launch a crew to the space station. Saturdays liftoff of NASA astronauts was the first from the U.S. in nine years. The crew will include Chris Ferguson, commander of the last shuttle flight who now works for Boeing.

Once on board the space station, Hurley said the capsule, newly named Endeavour after the retired shuttle, handled extremely well. He was the pilot on the last U.S. spaceship to visit the space station the last shuttle flight, by Atlantis, in July 2011. Until Saturday, SpaceX had launched only space station supplies or satellites. Tremor was going to join Earthy, a plush globe delivered to the space station on last years test flight of a crew-less crew Dragon. Even so, getting the two astronauts safely to orbit and then the space station had everyone breathing huge sighs of relief.

For the first time in nearly a decade, astronauts will blast into orbit aboard an American rocket from American soil, a first for a private company. SpaceX becomes the first private company to launch people into orbit, a feat achieved previously by only three governments: the U.S., Russia and China. Thanks for the great ride to space, Hurley told SpaceX ground control. A SpaceX capsule exploded on the test stand last year. For SpaceX and the future of public-corporate space exploration, the stakes on Saturday were extraordinarily high.

Were back in the race, as the SpaceX rocket lifted through clouds above Kennedy Space Center. Around him, spectators screamed, whistled and clapped after shouting out the countdown from the 10-second mark. Many spectators had been there just days earlier on Wednesday for the first launch attempt, which was scrubbed due to the weather. At Space View Park in Titusville, few spectators wore masks and there wasn't much social distancing. Now look at all the people who are here seeing astronauts leave from U.S. soil.___Follow Mike Schneider on Twitter: @MikeSchneiderAP

It will be the first astronaut launch from NASAs Kennedy Space Center since the last shuttle flight in 2011. (SpaceX via AP)CAPE CANAVERAL, Fla. Astronauts Doug Hurley and Bob Behnken join NASAs exclusive inner circle by catching a ride on a SpaceX rocket and capsule. Their destination is the International Space Station, where theyll spend one to four months before guiding their capsule to a splashdown in the Atlantic. Wife Karen Nyberg, a former space station resident, retired two months ago from NASA. As joint operations commander, he'll oversee the Dragons rendezvous and docking with the International Space Station.

A machinist from Buffalo, Wight drove 20 hours from Buffalo in upstate New York earlier in the week. The launch was a way to bring people together in an era of pandemic and unrest in cities this week, he said. Weve been bombarded with doom and gloom for the last six, eight weeks, whatever it is, and this is awesome." Sarah Bryants 14-year-old son, Brooks, is obsessed with space, and had written out a checklist of all the steps in the launch process. As enthusiastic fans of SpaceX, Alexis Mesnjak and Dominque Gallery know watching a rocket launch can take some patience.

SpaceX pressed ahead with its second attempt to launch astronauts for NASA a historic first for a private company but more stormy weather threatened more delays. Elon Musks company came within 17 minutes Wednesday of launching a pair of NASA astronauts for the first time in nearly a decade from the U.S., before the threat of lightning forced a delay. NASA Administrator Jim Bridenstine said managers were debating whether to bump the next launch attempt from Saturday to Sunday to take advantage of a slightly improved forecast at Kennedy Space Center. The Kennedy Space Center Visitor Complex reopened Thursday, after a 2 1/2-month shutdown, and within a few hours, all 4,000 tickets were snapped up for Saturdays launch attempt.

For the spectators gathered along the Space Coast on Wednesday for an astronaut launch, the rumbling thunder and darkening clouds were more worrisome than any pandemic. They turned out to watch the first launch with astronauts from Florida in almost a decade, and the first by a private company, SpaceX. About half of the spectators at the Titusville park wore masks as encouraged by health officials to stop the spread of the new coronavirus. I wanted them to see the flip side and get to see the next era of space travel," said Gatz, who lives about an hour away in Deltona.

(AP Photo/Susan Walsh)WASHINGTON President Donald Trump is hoping the first launch of American astronauts from U.S. soil in nearly a decade will give the nations spirit a boost after months of battling the coronavirus. Its the latest visit to an important 2020 battleground state as the president emerges from his White House bubble and expands his travel itinerary. Trump is encouraging states to loosen restrictions on economic activity put into place to slow the spread of the coronavirus. A Quinnipiac University poll last month found older Florida voters divided on Trumps handling of the coronavirus outbreak, with 47% saying they approved and 50% disapproving. Vice President Mike Pence got to Florida ahead of Trump and was to meet with the astronauts families and NASA officials before the launch.

CAPE CANAVERAL, Fla. – With the weather looking up, SpaceX and NASA officials vowed Tuesday to keep crew safety the top priority for the nation's first astronaut launch to orbit in nearly a decade. Veteran NASA astronauts Doug Hurley and Bob Behnken were set to make history Wednesday afternoon, riding SpaceX's Falcon 9 rocket and Dragon capsule to the International Space Station on a test flight. SpaceX has been launching cargo capsules to the space station since 2012. NASA hired SpaceX and Boeing in 2014 to transport astronauts to the space station, after commercial cargo shipments had taken off. Development of SpaceX’s Dragon and Boeing’s Starliner capsules took longer than expected, however, and the U.S. has been paying Russia to launch NASA astronauts in the interim.

The two NASA astronauts who will climb into the Demo-2 capsule atop the SpaceX Dragon rocket for Wednesday’s historic mission are launch veterans: Bob Behnken and Doug Hurley. They will lift off from the same launchpad at the Kennedy Space Center that hoisted the crew of Apollo 11 to the moon. Behnken was an experienced Air Force test pilot when he was first selected by NASA to join the astronaut corps in 2000. He last visited space on a shuttle mission in 2010. SPECIAL SECTION: Launch AmericaThis, by the way, is the first time Behnken and Hurley have flown together.
